Many studies have evaluated the viability of measuring the pulmonary vascular resistance (PVR) by non-invasive methods in patients with pulmonary hypertension, pulmonary thromboembolism, ischemic cardiopathy and valvular disease. The investigators have not found other studies which evaluate the PVR in elderly patients with COPD. The hypothesis is that in patients with COPD, the severity of obstruction, expressed by GOLD class, is associated with an increase of PVR.

right ventricular function and GOLD stages
To compare right ventricular function, evaluated by a non-invasive method such as echocardiography, with the GOLD stages in chronic obstructive pulmonary disease (COPD) patients.
Time frame: cross sectional
Right ventricular function and FEV1.
Compare right ventricular function, evaluated by a non-invasive method such as echocardiography, tricuspid annulus plane systolic excursion (TAPSE),pulmonary artery systolic pressure (PAPs) and fractional area change (FAC), with the GOLD stages in chronic obstructive pulmonary disease (COPD) patients.
Time frame: cross sectional
ECG and echocardiography parameters of cor pulmonale
The correlation between right ventricular function and the electrocardiographic parameters of cor pulmonale.
Time frame: cross sectional
Right ventricle function and 6M-WT.
Evaluate the correlation between the hemodynamic indices of right ventricle and the six minute walking test (6M-WT).
Time frame: cross sectional
